Jordan: Ancient Metallurgy of Social Sciences

It was not until about 1200 BC that iron became general for the production of tools because the temperatures needed to process the ore exceeded what most ancient kilns were able to reach. Pure iron has a melting point of 1,535°C. The limit of an ancient furnace was about 1,150°C. (Recall, by contrast, that copper has a melting point of
